People
who are creative, imaginative and prone to fantasy are more likely to have
vivid dreams at night and to remember them when they wake up, University
of Iowa research shows.

David Watson, a professor of psychology in the UI College of Liberal Arts
and Sciences, said that the more bizarre a dream was the more likely his
subjects were to remember it. Dream recall varied widely, with a few participants
remembering a dream every night and others never remembering a dream throughout
the three-month study. On average, participants recalled dreams three or
four days per week.

This study, which appears in the May 2003 issue of the journal "Personality
and Individual Differences," represents the largest and most comprehensive
analysis of individual differences in dream recall to date. Watson asked
193 college students to record each morning for 14 weeks what time they woke
up, what time they had gone to bed the previous night, whether they had consumed
alcohol or caffeine within four hours of bedtime, and whether they remembered
any dreams upon waking.

He found that neither sleep quality nor length of sleep was associated with
dream recall, although students who maintained inconsistent bedtime schedules
tended to report slightly more sleep- and dream-related experiences. There
also was a slight tendency for "evening people" to remember more
of their dreams.

Most significantly, Watson found individuals who are prone to absorption,
imaginativeness, daydreaming and fantasizing are particularly likely to remember
their dreams.

"There is a fundamental continuity between how people experience the
world during the day and at night," he said. "People who are prone
to daydreaming and fantasy have less of a barrier between states of sleep
and wakefulness and seem to more easily pass between them."

This research is an extension of Watson's earlier studies on mood and temperament.
He has studied circadian rhythms and differences between morning and evening
people, which led naturally to studies of sleep and dreams. Watson said studying
dreams is important to understanding what happens in the brain during sleep.
